my favourite thing is when I'm trying to click a button on a website, then it loads a bit more and suddenly jumps down so I end up hitting another button that I really did not want to press
Hundstrasse@gc I have a theory that websites do this on purpose
Jens Zalzala@Hundstrasse @gc Hmm, it's possible, but it's generally discouraged: https://web.dev/articles/cls
Usually when I see it it's due to poor implementation, or awful ad services, which serve different size ads which don't load until you scroll to them.
